Most likely, your Sound Card has a STEREO 1/8" Line Out.

If you are going to use your STEREO LINE IN on your Mixer, you will need an 1/8" STEREO Male split to Two 1/4" MONO Males (Red/White or some other mating colors).

Radio Shack sells this but the MONO ends are RCA. So, if you buy from Radio Shack, you will need to buy Two RCA to 1/4" Adapters, in which, you end up with more parts pieced together - the more parts the greater the possibility of something going wrong.

Hosa Technology, Inc. site:

sells a nice cable that is 10ft. (length I prefer when Computer has to be located further away, such as the FLOOR) having Part Number and Description of CMP-159 3.5MM STEREO TO TWO 1/4" PHONE, 10FT.

See Specs at this site:

You can search this site to find a Dealer who may either have it on hand or who may order it for you (I ordered three at once):

Hope this helps,
